Nanc is a free backendless CMS. Backendless means that you can use any Backend, cloud service like Firebase / Supabase or else, JSON file, or even Google table as a data source to manage with Nanc.
Nanc also includes the Server Driven UI engine, which is very tightly integrated into Nanc and allows you to create individual components and entire screens directly from your Nanc browser/desktop application, fully customizable, that can appear on your users' devices in the blink of an eye. At the same time Nanc Server Driven UI (aka Nui) - does not require the use of Nanc to realize all your ideas.
